Abstract: SIGNAL PROCESSOR                                ABSTRACT A signal processor (10) comprising a split pipelined parallel processor which processes data signals from external signal sources and provides signal processing functions utilizing a plurality of data formats. The signal processor (10) comprises an external interface (11) having a serial control port and a plurality of bidirectional parallel ports. The interface (11) transfers control and data signals between the signal processor (10) and external devices. The parallel ports are configurable as individual parallel ports or as coupled pairs which form a port having the combined data path of the two coupled ports. An arithmetic element controller (17) comprising a micropro-gram memory (18) and a control program memory (15) is coupled to the interface (11) which loads applications programs into the control program memory (15) and executes the programs. The arithmetic element controller (17) controls the process-ing of control and data signals in the signal processor (10). A plurality of pipelined arithmetic elements are coupled to the arithmetic element controller each comprising a data store memory (13) a multiplier (114) and a register and arithmetic logic unit (20). Each arithmetic element has its data store memory (13) coupled to the external interface (11) to receive and store data signals and to its multiplier (14) and the reg-ister and arithmetic logic unit (20) in order to perform fixed and floating point arith-metic operations on the data stored in the data store memory (13). These arithmetic operations are performed in accordance with application program and microprograminstructions contained in the control program and the microprogram memories. Thepresent invention provides for a high performance architecture for use with vector and matrix signal processing algorithms that minimizes the amount of hardware needed to implement them.

Title: Methods and apparatus for checking the integrity of data base data entries
Inventor: DAVEY SUSAN S
IPC: G06F11/08
Filed: 1990-07-09
Abstract: Abstract of the Disclosure A method and apparatus for testing the integrity of the data in a large data base is described. The constraints on the values of the data are represented by data descriptor records having the same format as the data records. These constraints specify intra-record constraints, inter-record constraints andconditional constraints, i.e., constraints which depend upon the satisfaction of some condition such as a particular data value. These descriptor records are compileddirectly into executable code which, in turn, can test each record of the data base for conformance with the constraints specified. Such code can be compiled "on the fly" as needed to test particular records, or compiled off-line and called whenever needed. The same facilities used to process the application data base records can thus be used to create, modify and delete the constraint descriptor records which may therefore form part of the same data base.

Title: Non-invasive torquemeter
Inventor: PARKER JOHN A
IPC: G01L1/24
Filed: 1990-09-07
Abstract: ABSTRACT          In the past in order to measure the applied forces to an object contactwith the object, modification of the object, or adding a heavy or a bulky addition to the object was necessary.  In the described method and apparatus for the non-invasive measurement of torque induced strain in an object, the photoelastic properties of certain materials is utilized. By attaching a small lightweight patch of photoelastic material to an object in such a manner as to allow it to be strained with the object, applied forces can be monitored, by observing the changes in the optical characteristics of the strained patch.  The observed changes can then be correlated into a value for the applied forces at a remote location. Since all that is necessary for observation is fiber optic cables, this measurement system is almost completely non-obtrusive.

Filed: 1991-10-22
Abstract: The present invention relates to a valve assembly (10) which is mounted on a part (piston unit 40) of an air motor (10) arranged for reciprocating movement in a housing (cylinder 12). The valve assembly includes a first valve unit (50), which is mounted on one side of the part (40), and a second valve unit (70), which is mounted on the other side of the part (40). The second valve unit is connected to the first valve unit (50) by means of the part (40) for common movement with the first valve unit relative to the part (40) when the valve assembly is switched as the part (40) reaches one of its two end turning-positions.

Title: High speed variable count mechanical stacker

IPC: B65G47/08
Filed: 1991-11-22
Abstract: Abstract of the Disclosure A pair of closed loop chains running in par-allelism have uniformly spaced apart paddles on them for transporting an article such as a pad between each paddle to a pad ejection station.   A shaft orbits about an axis which is parallel to the direction in which the paddle conveyor is moving.  The shaft car-ries a plurality of ejector rods which are mounted on a sleeve that is slidable reversibly axially on the orbiting shaft.  After the orbiting rods collectively eject a series of pads from the paddles, the shaft continues its orbital movement until it reaches the back side of the pads again.  While the rods are pass-ing through the paddles to eject the number of pads composing a stack, the sleeve on the orbiting shaft is translated axially in the same direction and at the same speed as the paddle conveyor is moving.   The sleeve is shifted by having a cam follower thereon come into contact with a stationary cam when the rods begin their passage through the spaces between the paddles.  When rods clear the spaces between the pad-dles, a spring restores the rods to their initial po-sition.  The orbiting shaft can be caused to dwell in its orbit to allow a selected number of pads to arrive on the conveyor at the ejection station before orbit-ing the rods to cause ejection of the articles is ini-tiated.
